Abstract: CENTERING A TIRE IN A MOLD               Abstract of the Disclosure The production of a very large tire by expanding the uncured unrestrained carcass or the tire to engage its crown region with the radially inward surface of a rigid circumferentially continuous centering ring.  The ring and the uncured carcass together are transported from the carcass expanding location to the tire curing mold which is adapted so receive and locate the ring and carcass together so as to prevent the mid-circumferential region of the carcass from shifting out of symmetry with the mold The ring forms a part of the mold for molding and curing the tire carcass. The inward surface of the ring is pro-vided with a pattern of grooves and ridges; the method and apparatus disclosed are particularly useful in the manufacture of a cured tire carcass adapted to combine with an endless tread assembly cured apart from and in-dependently or the tire carcass to make the complete tire.

Granted: 1979-08-21
Abstract: La présente invention concerne l'alimentation de balises à lampes-éclairs par l'énergie capacitive extraite d'une section isolée du fil de garde d'une ligne de transport d'énergie.  Le système d'alimentation comporte un circuit de transformation de l'énergie capacitive à courant alternatif du fil de garde en tension continue qui alimente au moins une des lampes-éclairs et un circuit de régulation monté en dérivation sur le circuit de transformation pour contrôler une valeur seuil de la tension continue alimentant les lampes.  Cette régulation s'effectue en détectant la valeur seuil prédéterminée de la tension continue aux bornes des lampes et en commutant à la masse l'énergie capacitive extraite du fil de garde lorsque cette valeur seuil est atteinte.  En outre, une impulsion générée à intervalle prédéterminée commande un circuit de mise à feu de chaque lampe-éclair lorsque celle-ci est sous une tension continue correspondant à la valeur seuil prédéterminée et régularisée par commutation shunt.

Abstract: ABSTRACT OF THE DISCLOSURE     A tone arm, designed for use with a semi- or fully automatic record player, is provided with an electromagnetic drive mechanism.  The tone arm is supported by two separate shafts so as to be rotatable in both the horizontal and vertical directions.  A bobbin, to which horizontal and vertical drive coils are circumferentially attached, is arranged coaxially with that shaft permitting horizontal movement.  A permanent magnet is arranged facing the drive coils,  Interaction between the permanent magnetic field and those generated by energization of the drive coils causes either a torque or a vertical force to be imparted to the bobbin and thus effect a corresponding movement of the tone arm.

Abstract: ABSTRACT OF THE DISCLOSURE     An improvement is provided in a process for separating a C2+-hydrocarbon fraction from compressed CO2-containing natural gas by rectification, wherein the compressed natural gas is, prior to rectification, subjected to partial conden-sation and engine-expansion steps to achieve the desired pres-sure and temperature conditions in the rectification column, and wherein the column is fed by resultant condensate of natural gas.  The improvement includes the step of conducting the engine expansion of the natural gas to a point well above the temperature at which the CO2 would otherwise precipitate out, and recovering, from the engine-expansion step an unliquefied gaseous fraction; then passing that fraction in indirect heat exchange realtionship with engine-expanded overhead product from the column; and then feeding resultant partially condensed fraction to the top of the column.   In consequence of these steps, and particularly the second step, peak cooling and partial condensation of the fraction is achieved.

Abstract: ABSTRACT OF THE DISCLOSURE                  Apparatus for crushing fragments of mineral material comprises a rotary crusher mounted above, and co-operating with, a scraper-chain conveyor.  The rotary crusher has a cylindrical body provided with a-plurality of first, second and third rows of chisels.   The chisels are detachably mounted in holders fixed to the cylindrical body.   The chisels are all the same, but the holders are of different sizes so that the chisels of a first set have a longer radial reach than the chisels of second set, which in turn have a longer radial reach than the chisels of a third set.   Each first row has chisels of the first and second sets, and each of the second and third rows has chisels of the third set. The provision of the chisels of the first and second sets having longer radial reaches enables the mineral material to be drawn into the crushing gap between the rotary crusher and the scraper-chain conveyor and broken up more efficiently.

Abstract: A B S T R A C T         This invention provides an arrangement for optical coupling, including interconnecting optical fibers, coupling a source to the fiber and coupling a fiber to a detector.  The connector may comprise an objective lens and an immersion lens provided by opposed cavities in a transparent medium, each contain-ing an index of refraction material, with the optical fibers to be connected inserted into the opposed cavities.  Cavities also are used in source-to-fiber and fiber-to-detector coupling, being defined by surfaces of revolution and providing an aligning and positioning means.  By appropriate selection of the indices of refraction of the index of refraction material and the transparent medium, the light from the emitting device is refracted and transmitted to the receiving device, resulting in low-loss light transmission.  Means may be provided for changing the emittance angle so as to cause the light to be within the acceptance angle of the receiving device.  In one embodiment at least one inter-mediate lens is positioned between the objective and immersion lenses.

Abstract: ABSTRACT               "BI-DIRECTIONAL IMPULSE SHEAR WAVE GENERATOR             AND METHOD OF USE"             In accordance with the present invention, an impulse generator of high portability is provided using a pair of guil-lotinized, separately activated hammer/anvil sub-assemblies. Since each sub-assembly is horizontal positioned, say in contact with the earth from a position below the wheel of an exploration truck, the equivalent of the "flying blade" of a guillotine, i.e., a weighted hammer element, must be provided with horizontal movement. This is done by tensioning a plurality of springs attached between the hammer element and a rectangular main frame.             During cocking and release of the hammer, the explo-rationist is provided with a series of visual signals in the form of deactivated and activated panel lights.  These signals are automatically provided by controller means of the present invention. Release of the cocked hammer, however, is operator controlled for safety reasons say by activation of a latching means attached to the main frame of the assembly.
